<title>DESCRIPTION</title>
<para>This manual page documents briefly the
<command>&dhpackage;</command> tool.</para>
<para>This manual page was written for the &debian; distribution
because the original program does not have a manual page.</para>
<para><command>&dhpackage;</command> writes the last 10
seconds of audio _before_ the button press and everything from now
on up to the next button press into a WAV-file. </para>
<para>The idea is that you doodle away with whatever is kicking
around in your studio and when you heard an interesting noise, you'd
press record and capture it, without having to try and recreate it.
</para>
<para>Run it with <command>&dhpackage;</command> then connect it up with
a jack patchbay app. To start recording click in the window, to
stop recording click in the window again.</para>
<para>It will create a file following tm-*.wav, with an
ISO 8601 timestamp, eg tm-2003-01-19T20:47:03.wav. The time is the
time that the recording starts from, not when you click.</para>
<para>It uses the JACK audio connection kit, an API that lets audio
application communicate with each other and share audio data in
realtime. </para>
<para>The generated file will be a W64 file, a valid but
unusual WAV format that might not be recognized by some
programs. Binaries linked with libsndfile should be able to
read it. Also, note that the sample rate of the file with be
the same as the sample rate <command>jackd</command> is
running at when <command>&dhpackage;</command> is started.</para>
